IMPROVEMENT IN SIDE-HILL PLOWS.l

Specification forming part of Letters Patent No. 157,130, dated November 24, 1874; application filed August 25, 1874.

To all whom it may concern.-

Beit known that I, LEwIs L. IvERsoN, of Decorah, in the county of Vinneshiek and State of Iowa, have invented a new and valuable Improvement in Double Flows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings makinga part of this specification, and to the letters and figures of reference marked thereon.

Figures l and 2 of the drawings are representations of side views of my double plow. Fig. 3 is a plan view, Fig. 4 is a rear View, and Fig. 5 is a detail view, of the same.

This invention has relation to double reversible hillside plows wherein two complete mold-board plows are connected to or formed on a single inclined standard, which can be turned in the beam for bringing either plow into operation at pleasure.

The improvements which I have iliade consist mainly in a springstay at the rear end ofthe plow-beam, which will receive either one of the plow-points and sustain the plows in the desired position for operation, at the same time allowing the plows to be readily adjusted. It also consists in aholding-down loop, in combination with the stay at the rear end of the plow-beam for resisting shocks while plowing stony land.

In the annexeddrawings, A designates the beam of the plow, and B B are the handles thereof. C C are two mold-boards, which are both alike in form, and which are applied to a single land-side plate, D, so as to form two plows, each one being complete in itself, one being intended for right-hand and the other for lefthand plowing. The standard E of these two plows is passed through a metal tube, which is confined in an inclined position in the beam A, and on the upper end of the standard a nut, a, is screwed, as shown in Figs. l, 2, and 3.

The plows shown by Fig. 5 have hinged mold-board wings b applied to them, which will greatly shorten the distance between the plow-points, and at the same time give all the breadth of mold-board required. Vhen these hinged wings are employed they will have a cranked arm, c, secured to their upper ends, which arm will be received into a casting on the plow-beam, for the purpose of adjusting the wings properly when the plows are adjusted. At the rear extremity of the plowbeam is a stay-piece, d, having a recess in its bottom to receive the points of the plows. This stay-piece is secured to a spring-plate, S, which is fastened on top of the beam A, and the edges of the stay (l are under-beveled, so that when the plows are swung around the point of the rearmost plow will spring up the stay and engage in its recess. In front ofthe stay-piece d, and rigidly secured to the beam A, is a loop, g, against which the rearmost plow presses when the front plow is in proper position for working. This loop g resists the downward thrusts ot' the front plow-point in plowing stony land. Lateral displacement of the front plow-point is prevented by means of a brace, e, which is pivoted to the under side ot' the beam A and hooked into the upper part of the mold-board of the rear plow. This brace is made of two extensible sections, which can be shortened or lengthened for giving more or less land to the working plow.

What I claim as new, and desire to secure by Letters Patent, is-

l. The spring stay-block d, combined with the reversible double plow, substantially as described.

2. The loop g, combined with the reversible double plow, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence,

of two witnesses.
